Invasive Species Research

Research is an important part of any effective invasive plant management strategy. The River to River CWMA works with partners to identify research needs and to seek out funding opportunities to meet those needs. We are currently initiating new research in the following topics:


Below is a list of some articles by CWMA partners involving research on invasive species in Southern Illinois.
